Middle English
fromOld French
fromLatin c絧ula[ bond, pair ]
couple pair brace yokeThese nouns denote two individuals of the same kind together. <SKW> Coupledoes not necessarily imply more than association:
a square dance performed by four couples. The term may also mean simply 揻ew?
a couple of minutes;
a couple of books. <SKW>Pair stresses close association and often reciprocal dependence of things (
a pair of gloves;
a pair of pajamas); sometimes it denotes a single thing with interdependent parts (
a pair of scissors;
a pair of spectacles). <SKW> Brace refers principally to certain animals or game birds (
a brace of hounds;
a brace of partridges), and yoke to two joined draft animals (
a yoke of oxen).
When used to refer to two people who function socially as a unit, as in a married couple, the word couple may take either a singular or a plural verb, depending on whether the members are considered individually or collectively:
The couple were married last week.
Only one couple was unaccounted for. When a pronoun follows, they and their are more common than it and its:
The couple decided to spend their (less commonly its) vacation in Italy. Care should be taken that the verb and the pronoun agree in number:
The couple have their (less commonly has its) primary residence in New York. ?Although the phrase a couple of has been well established in English since before the Renaissance, it has been criticized on several grounds. Grammarians used to insist that a couple of should be used only to refer to things closely linked to one another and so was improperly used in phrases such as a couple of years ago. This objection has not been heard in some time and was never well supported. Modern critics have sometimes maintained that a couple of is too inexact to be appropriate in formal writing. But the inexactitude of a couple of may serve a useful communicative purpose, suggesting that the writer is indifferent to the precise number of items involved. Thus the sentence She lives only a couple of miles away implies not only that the distance is short but that its exact measure is unimportant. Furthermore, a couple of is different from a few in that it does not imply that the relevant amount is relatively small. One might say admiringly of an exceptional center fielder that he can throw the ball a couple of hundred feet, but not, except ironically, a few hundred feet, which would suggest that such a throw was unremarkable. The usage should be considered unobjectionable on all levels of style.

When used to refer to two people who function socially as a unit, as in a married couple, the word couple may take either a singular or a plural verb, depending on whether the members are considered individually or collectively:

The couple decided to spend their (less commonly its) vacation in Italy. Care should be taken that the verb and the pronoun agree in number:
这对夫妇决定在意大利度过他们的（很少用 its） 假期。应当注意动词和代词在数上要一致：
The couple have their (less commonly has its) primary residence in New York. ?Although the phrase a couple of has been well established in English since before the Renaissance, it has been criticized on several grounds.

这对夫妇（很少用 has its ） 最初的住处在纽约。 尽管 a couple of 这个短语在文艺复兴之前就已在英语中形成，它仍受到多方面批评。语法学家过去坚持认为 a couple of 应该只用于指互相之间紧密相连的东西，所以在 a couple of years ago这样的短语中用是不适当的。这样的反对意见长时间没有人提起了，也从未受到太多支持。现代批评家有时也认为 a couple of 太不精确，不能很恰当地用于正式的写作中。但 a couple of的不精确性也有一种很有用的传达交流的意图，表明作者对于所涉及的事物的精确数目并不太关心。因此 她住的只有几英里远这个句子不仅表明距离很远，同时也表明精确测量是不重要的。另外 a couple of与 a few 的不同还表现在它不表示有关的数量是相对来说小的。如果夸赞一个优秀的中外野球手，可以说 他能把球抛几百英尺远，若非如此的话，排除反意的可能， a few hundred feet指抛这么远并没什么稀奇之处。这种用法在各种文体上都是无可辩驳的
